Hey! Just got back. Can't really believe that we made it there Covid free, stayed Covid free there and came back covid free. We had prepped for the possibility of getting it (which is why we only did Orlando and stayed for over 2 weeks in one location). Was looking forward to testing out the
travel insurance 
Unfortunately now, I can't really review HeyMondo (other than it was cheaper than Covermore). Grateful that we didn't get sick though.
It's pretty busy now that I'm back, so I'm gonna just type a few things in here and then monitor this discussion thread for any questions (which I'd be happy to answer). We tried a quite a lot of new things while we were there. Hopefully this will help anyone who is going soon:
1. Turo: Wow! we loved using Turo (my sister had used it before and so we were willing to give it a go). It's like an AirBnB for cars. But it's better than the very expensive regular car rental because the owner drives the car to you (or to the airport directly) and picks up the car from you (or the airport). Saved us a lot of time, plus it was much cheaper than car rental
2. Google Fi: We got US sims through Google Fi (you will need to create a US App Store account). $30 USD for a month of unlimited calls, text and 32 gigs of data at high speed (unlimited and throttled after that). Easy to set up (I had an eSIM, meaning that they didn't even need to send me anything .. but the rest of the family had regular SIMs). Worked like a charm
3. PCR Test: Found a place that did it for $125 (with same day results). Not sure that is relevant now
4. Fiji Airways: Super long flight (our flight back was Orlando to LAX with Delta, and then LAX-Nadi-Sydney-Melbourne .. 35+ with layovers). It was ok, but very good for the price (we had 5 of us). Would fly them again.
5. AttractionTickets from UK: Wow, those 14 day tickets were fantastic!
6. WDW: So many things have changed and the way you organise and plan the parks is now so different. Probably too hard to type it in here, but we tried a range of different things (eg.
Genie+, Extra Magic House etc.). Definitely get to know the
MDE app well. Happy to answer questions on here
7. Resorts: My ranking of the ones we stayed at: Grand Floridian Villas, Riviera, Polynesian and then Old Key West. Not that OKW was bad .. we had a 2 BR there and it was actually really good to end with extra space to pack and unwind. Used the resort a lot at OKW
Anyways, just a quick brain dump from me. Happy New Year!
